(Cl. "9S-34) 10 Claims.

l This invention relates to photography and, more particularly, to photographic cameras in which all of the normal manual operations for making an exposure are automatically performed `by the camera mechanism and in which the exposed sensitized material is fed into -a lmagazine for removal at any time `from the camera.

Automatic cameras in which the actuation of a single but-ton, or of a vmea-ns not a part of the camera, results in tripping of the shutter and advancing of the sensitized material or lm are well known. However, in this -type of camera, the film is usually contained in rolls providing a designated number of exposures, and the iilm is not removable at any time unless some of the film is wasted by opening the camera before :the last exposure has .been made. A further Idisadvantage in fully automatic cameras is that no provisions are made for winding the last exposed area into a position for severing it from the remainder of the iilm and then being able to wind the severed iii-m into a magazine :independently of the normal means for advancing the ilm frame by frame.

In applications of photography to industrial use, the camera is vusually set up at a station and actuated by movement of the object to be photographed or at predetermined intervals Without any attendance `by ,an operator. The camera, therefore, must `of necessity Vbe com pletely automatic and contain suflicient iilm for a large number of exposures so .that frequent reloading is eliminated. In a camera intended for such industrial purposes, it is also a primary requisite that the exposed portion of the lm strip is readily available, that is, the exposed lm must be removable from the camera .at any time without waiting for .exposure of the entire ilm supply, particularly if the photographic study is to be made over a considerable period of time. This is accomplished in the present invention by providing a lm take-up magazine into which the exposed lm is advanced and by providing a manually operable Winding member which can be actuated at any time to wind the last exposed iilm area beyond a severing means, to actuate a severing means, and then to wind the severed and exposed lm strip completely into the magazine. The means for winding the exposed area of nlm into the magazine is independent oi the drive means for advancing lthe iilm strip frame by frame and also serves to release a locking means to permit ejection of the magazine and to render inoperative normal operation of the camera until an empty @magazine is again inserted in the chamber.

2 The primary object of the invention, therefore, is to provide a photographic camera which is entirely automatic in its normal sequence of operation Wherein the film strip is advanced frame by frame into a take-up magazine and in which the lm strip may at any time be advanced, severed, and the severed portion oi the strip advanced into the magazine independently of the normal automatic operation of the camera.

Another .object of the Vinvention is to provide a fully automatic camera in which a manually operable Winding means can be actuated at any time to advance the last exposed lm area beyond a severing means, to tension the nlm strip between the severing means and the take-up core .of the magazine duringl severing of the iilm strip, and then advance the severed film strip into the take-up magazine.

Still another object of the invention is to provide a fully automatic camera in which a drive member for rotating the magazine take-up core is operatively connected to the automatic film advancing means and to a manually operable winding means vand adapted to be rotated in the same direction upon actuation oi either of said means.

And yet another object of the invention is to provide a fully automatic camera in which a manually operable winding means may be actuated at any time to advance the lm strip into a take-up magazine and to release a locking means to permit ejection of the magazine from the take-up chamber.

And still another object of the invention is to provide a fully automatic camera in which a manually operable winding means may be actuated at any time to advance Vthe ilm strip into a takeup magazine and to render inoperative normal automatic functioning of the camera until another magazine is inserted in the magazine-chamber.

Other objects and advantages Will be apparent to `those skilled in the art from the description which follows.

The objects of the linvention are embodied in a camera .having a. .chamber adapted to receive a magazine, a guideway provided with an exposure aperture .and for directing a sensitized material to .said nham-ber, a 'locking means for holding said magazine in said chamber, a severing means between said .guideway and said chamber for severing :said `sensitized material, a magazine ejecting means movable to a retracted position, by 'insertion `of :a kmagazine into said chamber, and maintained in said retracted position by the engagement of said magazine with said locking means, a winding assembly including a manually operable winding drive member and a take-up drive member in said chamber adapted to engage and to rotate the take-up of said magazine and operable at any time for moving the area of said sensitized material at said exposure aperture past said severing means and for moving the severed sensitized material into said magazine, an advancing means includinga rotatable member for engaging and moving a predetermined amount of sensitized material past said exposure aperture and a prime mover for imparting rotation to said rotatable member, a unidirectional clutch means including a drive member and between said rotatable member and said" prime mover, a second unidirectional clutch means bef;

tween said winding drive member and said takeup drive member and including -a winding driven Aprovided with a supply chamber I I, a mechanism chamber I2 and atake-up or magazine chamber I3, each having a cover I4, I and I6, respectively. The lm lsupply reel or'magazine I1 is member engaging said winding drive member, ya.

driven member operatively connected to the drive member of said rst-mentioned clutch means, a clutch drive member on ysaid winding driven member and said driven member, and clutch driven members in engagement with said clutch drive members for rotating said take-up drive A member, both of said unidirectional clutch means being rotated in lthe same direction and independently capable of rotating said take-up driveV member, and an actuating means operatively connected to said locking means and said severing means and movable with said winding assembly for actuating said severing means after saidI area of sensitized material has been moved past are contemplated by the invention and claimed',

rotatably mounted on spindle I8 in chamber II and is maintained in a properly aligned position by the boss I9 on cover I4. The front wall of the chamber I2 is provided with a threaded aperture 28 for receiving the lens mount 2|. The wall 22 which separates the mechanism and supply chambers is provided with an aperture 23 throughv which the lm strip is advanced from the reel I1 to the mechanism chamber. The lm strip passes between the driven rubber roller 24 and the idler spring-biased rubber roller 25 and into the guideway 26. The guideway 28 comprises a plate 21 which extends vertically from the rollers I 24 and 25 to a point beyond the rleld of the camera lens Where it is formed with a arcuate portionand a horizontal extension, a plate 28 with the vertical extension of the plate 21 provides the vertical guideway, and a plate 29 with the horizontal extension of the plate 21 provides a horizontal guideway to the magazine chamber I3, see Fig. l. The plates 21, 28 and 29 are relieved centrally in a well-known manner so that said plates engage only the edges of the iilm strip, and the plate 21 is provided with an exposure aperture 38 in alignment with the camera lens. A shutter 3I is mounted between the camera lens and the vertical portion of the guideway 26 and is actuated in a sequence described hereinafter by the link 32 connecting the shutter to the solenoid 33, see Figs. 1 and 3.

' The advancing means for automatically advancingthe iilm strip by a predetermined amount for each exposure, see Figs. 1 and 3, comprises a prime mover or a circular solenoid 35, which is mounted on the bracket 38, the shaft thereof oscillating the gear 31 on the opposite side of said bracket, see Fig. 3. The gear 31 meshes with a gear 38 on the stub shaft 39 which is journaled in the mechanism plate 4U and the bracket 36. A drive member or pulley 4I is secured to shaft 39 adjacent the plate 40. Since gears 31 and 33 are oscillated, the gear 38 is provided with an extension on which the pawl 42 and the formed lever 43 are pivotally mounted. The pawl 42 is spring-biased into engagement with ratchet 44 which is secured to shaft 45 aligned with stub shaft 39, said shaft 45 being journaled in a U- shaped bracket 48 mounted on bracket 3B. The ratchet 44 and pawl 42 constitute a unidirectional clutch means between shaft 39 on which pulley 4I is fixed and shaft 45 on which sprocket shaft 45 between the legs of bracket 46 and engages the film perforations to move the film strip in a manner about to be described. The plate 21 is provided with suitable grooves for the sprocket teeth. A pulley 48 integral with the ratchet 44 drives roller 24 by means of the belt 49.

rihe bracket St has integral therewith an extension 59 which lies in the path of pawl 42, and bracket 46 is provided with an extension 5| which arrests the motion of solenoid 35. The extending shaft of solenoid 35 has xed thereto a collar 52 provided with detents 53 and a bifurcated member 59 which acts as a stop for the solenoid in its released position. The member 54 is adjusted to engage the proper detent in collar 52 for movement therewith and for advancing the proper amount of nlm in accordance with the camera lens to be used. A proper mask, not shown, is also inserted in guideway 21 at the exposure aperture. A spring 55 connects the solenoid 35 with a pin on wall 55.

The lever 133 is pivotally connected to the arm l of bell-crank lever 5S which is pivotally mounted at 59 on boss 5b in chamber see Fig.

1. The other arm Si of 1lever 51 carries a loopforming roller F52. The film strip path from reel l1 is around roller 52, through aperture 23, and into the bite of rollers 24 and 25.

The cover l5 carries a stub shaft 53 which has a tongue for engaging a slot in the end of shaft 45 and is freely rotatable in boss 64 of said cover. A. -pivoted handle 'E55 is provided with an aperture for engaging the squared end of shaft 63 in a well-known manner and in its inoperative position is folded against cover l 5, as shown in Fig. 3.

The wall 55 is provided with an aperture 68 through which the film strip is advanced into the magazine chamber I3. The magazine 69 which is inserted in said chamber may be of the type .'f

disclosed and described in the copending U. S. application filed February 17, 1949, in my name and that of R. A. Gordon and having Serial No. 76,906, now Patent No. 2,578,283, dated Decemher 11, 1951. 59 is driven through gear 51 in the magazine which meshes with the gear or drive member contained within chamber i3. The gear 10 is mounted on a shaft 1| which is journaled in one wall of the chamber and a wall of the casing, see Fig. The shaft 1| has rotatable therewith, see Fig. 6, a ratchet 12 and a ratchet 13 with a pulley 14 between said ratchets and a gear 15 freely rotatable on said shaft, see Fig. 6. The pulley 14 is connected by the belt 16 to pulley 4|, and the gear 'i5 meshes with the gear sector 11'. Resilient drive members 13 and 19 are fixed to the hubs ci" the pulley 1d and the gear 15, respectively. From the description hereinafter it will. be noted that the elements rotatable with the shaft 1i and freely rotatable thereon, in effect, constitute a second unidirectional clutch means for rotating the drive member or gear 10 to rotate the take-up of the magazine in chamber I3.

The winding assembly comprises an external manually operable handle Si which rotates the shaft S2 journalled in the wall of casing l0 and a bearing St on wall 55, the gear sector or winding member 11 being rotatable with shaft 82 and meshing with gear 15. The gear sector 11 carries therewith a flat arcuate plate` 84 which is provided at one end with a substantially radial extending surface terminating in a lug-like extension 95 and serves as the holding means casing I0 above magazine chamber |3 and which.

The core or take-up of magazine has a locking member or extension 89 and an actuating member or portion 99. The lever 81 is urged toward magazine '$9 by spring 9| for engaging a detent 92 in the camera casing by which the magazine is held in position in the chamber.

rihe severing means, see Figs. 1, 2 and 5, comprises a plate 94 which is slidably mounted in the retaining block 95 on wall 55, and a knife edge or plate 96 fixed to plate 94. The plate 94 is maintained in its upper position by the spring 91 and in this position permits free passage of the film strip from the guideway 25 through the aperture 68 and into the magazine 69.

The ejecting means, see Figs. 1, 2, and 5, comprises a lever 99 pivotally mounted at |09 on boss lill extending from the side wall of chamber I3, a pin |62 extending through lever 99 and having one end thereof engaging the inner arcuate surface of plate 84 in the retracted position, as shown in Fig. 1, or the radial surface 85 and extension 86 in the ejecting position, as shown in Fig. 2, and the other end thereof passing through the arcuate slot 93 for engaging a suitable detent |94 in the side wall of magazine 69. A coil spring |05 tends to urge the lever 99 into its ejecting position.

The actuating means, see Figs. 2 and 5, comprises a cam |01 having a cam surface |99 for engaging the plate 94 of the severing means and al cam surface |99 for engaging the actuating member 99 of the locking means. The cam is secured to shaft 82 and is rotated with sector 1l upon actuation of handle 8|, the shaft and its associated parts being returnable to their normal positions by the coil spring |9.

The cooperation between the various elements and parts of the camera can best be understood from a description of its operation in conjunction with the schematic wiring diagram of Fig. 7. The winding assembly, the holding means, the severing means, the ejecting means and the actuating means are normally in the positions shown in Fig. 2 until a magazine is inserted in the chamber 3. As the magazine 59 is inserted into the chamber I3, the detent |94 engages the pin |02 and moves it along surface 85 toward the inner arcuate surface of plate tid and at the same time moving lever 99 about its pivot |00. When pin |92 reaches the arcuate surface, the spring lli) returns handle 8|, gear sector 11, and cam |01 to their winding position, the cam surface |99 permitting locking member 89 to engage the detent 9?. on the magazine for maintaining the magazine in the chamber against the action of the spring 55, and the cam surface |98 permitting the spring 91 +ro return the plate 94 to its upper position for opening the aperture 5B into the magazine chamber |3. When the magazine is in position, gear 19 will be in mesh with gear 51 on the magazine, and gear sector 11, then in its winding position, will have closed the switch H2. The nlm supply is then placed in the chamber by sliding the reel |1 on the spindle I8. The lm strip is threaded around roller 52 and pushed through aperture 23 until the leading end of the lm strip enters the bite of the rollers 24 and 25. The chamber is then enclosed by securing the cover i4 in position. The handle 65 is moved from its fold-down position to its winding position in which' it engages the square end of the stub shaft 63. Upon rotation of the handle 65 in a counterclockwise direction, see Fig. 1, the shaft 45 is rotated through the tongue and groove connection between shafts 45 and 63, sprocket 41,

ratchet 44 and pulley 48 being rotated therewith. Since ratchet 49 is rotated in a counter-clockwise direction it moves freely under the pawl 42 without rotating the pulley 4|. Pulley 43 through belt 49 drives the roller 24 and the film strip is moved through the guideway 26, beneath the severing knife 96, through the aperture 68 and into the magazine 69. The leading end of the lm strip may be secured to the take-up core of the magazine 69 in a manner described in the above-mentioned co-pending patent application. The handle 65 is given a suicient number of turns to insure that any film which was fogged during loading or threading is advanced into the magazine. The camera is then ready for making exposures and the various parts are in the positions shown in Figs. 1 and '1.

The automatic operation of the camera is started upon closing the line switch II3, see Fig. 7, thereby energizing the timing motor I I4. Timing motor I I4 rotates an actuating cam I I5 which opens and closes switch I I6 for controlling energization of solenoid 35. In the present instance, the timing motor and cam provide for kone exposure a second, although by providing a suitable gear train or by altering the cam, the number of exposures per minute can be increased or decreased. Further, since the camera has been designed primarily for industrial use, actuation of the switch II6 may be controlled by means of a photocell, a tripping circuit or by any one of a number of other means, depending on the conditions under which the camera is to operate or the type of subject to be photographed.

Upon each closing of the switch IIB, the solenoid 35 is energized and its rotary motion is transmitted from gear 31 to gear 38 for rotating stub shaft 39. As gear 33 is rotated, pawl 42 moves therewith engaging ratchet 44 to rotate pulley 43 integral therewith and shaft 45 to which v sprocket 41 is secured, thereby moving the film strip through the guideway 26 and toward the magazine 69. As pawl 42 is moved with gear 38, lever 43 is moved vertically to rotate lever 58 about its pivot 59 thereby moving roller 62 toward aperture 23 to permit movement into aperture 23 of the lm strip loop formed thereby. The pulley 4| being fixed to shaft 39 rotates pulley 14 on shaft 1I through belt 16. As pulley 14 is rotated, drive member 18 engages the ratchet 'I2 to rotate shaft 1I and gears 10 and 61, thereby rotating the take-up core of magazine 69. Movement of the sprocket 41 is arrested when pawl 42 engages the extension 50 on bracket 36 and coincides with the engagement of member 54 with extension 5| on bracket 46. When smaller film areas are exposed, because of a different camera lens being used, member 54 is adjusted to one of the other detents 53 in collar 52 toarrest movement of pawl 42 before it reaches extension 50. This adjustable stop controls movement of the solenoid and it is at this time that the solenoid 35 is deenergized by cam |I opening switch ||6. At the same time, link 43 is in the dotted line position as indicated in Fig. l and has closed shutter switch |I1, thereby energizing the solenoid 33 for actuating shutter 3| and exposing the lm area just advanced into the exposure aperture. In proper timed relation to the actuation of the shutter, the shutter operating solenoid 33 trips switch I I8 for energizing a light source ||9 through a suitable synchronizing circuit for synchronizing energization of the light source with the actuation of the shutter.

' Upon Vdeenergization of solenoid 35 by opening of switch I I6, the spring returns the solenoid to its initial position. The gears 31 and 38, therefore, are rotated in the opposite direction, pawl 42 moving over ratchet 44, pulley 14 rotating freely on shaft 1I, and drive member 18 moving over ratchet 12. To prevent rotation of sprocket 41 in a direction opposed to the normal movement of the film strip, a fibre or cork disc |22 is adjusted thereagainst by the screws |23. As pawl 42 is returned to its normal position with gear 38, the link 43 is moved downwardly to rotate lever 58 in a clockwise direction. Since the film strip is held against movement in the guideway 26 between rollers 24 and 25 and sprocket 41, the clockwise movement of arm 6| withdraws film from reel |1 to form a loop for the next advancement of the film strip. With this arrangement the lm strip is relieved of any undue stresses imparted thereto by the sprocket quickly withdrawing film directly from the reel. The return of the various elements to their normal positions takes place during the time interval in which the switch IIB is in the open position, and the complete cycle of lm advance and exposure takes place within a second every time the cycle is repeated.

The handle 3| may be operated at any time and after any number of exposures have been made to sever the lm strip and release the magazine 69. Immediately upon movement of the handle 8| and the sector 11, the normally open switch II2, which is held closed by the sector 11 in its winding position, is opened thereby breaking the circuit through the D. C. rectifier I2I and rendering the camera inoperative. If the switch II2 were not provided and the camera was rendered inoperative only by opening switch I3, then it would be possible to close switch I3 and start the camera cycle without a magazine in the chamber or without the handle 8| in its winding position, and the film would become jammed in the guideway behind the knife 96. Gear sector 11 rotates gear 15, and the drive member 19 thereon picks up ratchet 13 on shaft 1| to rotate the shaft in the same direction as when rotated by pulley 14. The shaft 1| rotates gear 10 and through gear 61 the take-up of the magazine 69. Since pulley I4 is freely mounted on shaft 1I, the ratchet 12 merely rotates under drive member 13 and there is no motion transmitted to pulley 4I and shaft 39. As the take-up core is rotated, the lm strip is drawn into the magazine, thereby rotating the sprocket 41 and rollers 24 and 25 by means of the film strip. In this instance, also, ratchet 44 moves under pawl 42 without imparting any motion to shaft 39. The gear sector 11 and the drive to the take-up of the magazine 69 is of such a ratio that a quarter revolution of handle 8| is sufficient to wind the last exposed area of film completely into the magazine before sector 11 reaches the end of its movement. The cam surface |08 is so disposed radially on shaft B2, that it actuates knife 96 to sever the lm strip immediately after the last exposed area of lm has moved past the knife. This point, however, is not at the end of the movement of sector 11, since the end of the film strip extending out of the magazine and through the aperture 68 must still be wound into the magazine by further movement of sector 11. By maintaining the lm strip movement continuous, the film strip is tensioned between the knife 96 and the take-up core of the magazine during the severing operation. This arrangement produces a cleaner cut and eliminates the need for disrupting movement of the take-up. When sector 11 reaches the end of its movement, the cam surface |09 will have'been rotated to a point Where actuating member 9G will have pivoted lever B1 to a position Where locking member 89 will be freed from detent t2. At the same time, the surface 85 of plate 8A will have reached a position opposite pin |02 and spring 105 Will then be free to move lever 9S to its ejecting position for moving the magazine 69 to the position shown in Fig. 2, the pin |i2 being held against further movement by lug 86 on plate 84. The various parts, therefore, are then in the l positions shown in Fig. 2 and upon insertion of another magazine are returned to their initial position as hereinbefore described.

From the foregoing description, it can be readily appreciated that the severing of the film takes place before the Winding of the lm stripY into the magazine is completed and that the magazine is not unlocked or ejected until the iilm strip has been :fully wound into the magazine. Also, the clutch means which permit rotation of the take-up drive member through either the nlm advancing means or the winding assembly are rotatable in only .one and the same direction. Since other modications of the invention are possible, the scope of the invention is not to be limited to the illustrated embodiments but is dened by the appended claims. Y
